Does anybody know where I can get the magnetic add-a-number pad?

You can look for the Kozar Prediction Pad. Many magic dealers carry it.

Any reason why you want to use a magnetic pad?

I have worked with a few different pads and methods, and find that I much prefer E. Raymond Carlyle's version. You can find it here: http://carlyletouch.com/PageOne.html

You can make it yourself, and the presentation is superb.

I wouldnt go for a magnetic one neither.Supposing a spectator shuts it before you want them to..?
Oops!

For over 25 years I have used one of the simplest methods for the pad...for laypersons...Most everyone on here should already know it. It has never, never failed me. Real people just don't think of it.

I like my Dangle Book.

I've used them all, but now I use the Bavli dry erase board. As far as the Kozar being shut by the spectator, put a rubber band around the bottom.

Just a thought...using the Kozar pad you could do Autome and the add-a-no effect with the same numbers. When done with the same numbers withour any further re-use of the pad it is quite impressive.
